Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed May 4, 1908. Serial No. 430,754.

To all whom it may concern:

Be it known that we, DANIEL LEWIS and KATHARINE Lnwrs, both of Buffalo,in the county of Erie and State of New York, have invented certain newand useful Improvements in Cooking-Pans, of which the ollowing is aspecification.

Our invention relates to cooking-pans and more especially to that typeof pan designed for cooking meats, or for cooking or baking otherarticles of food.

The primary object of our invention is the production of a one'piece panso fashioned that its dished portion is seamless and well reinforced andthat all sharp corners or angles are dispensed with, thus preventing chiping of the enamel.

nother object is to so construct the pan that all parts in or on whichgrease and dirt can lodge will be easily accessible for clean- A stillfurther object is the roduction of a one-piece pan in which the si es ofthe pan are made of two thicknesses of metal in physical contact, with ahollow rim at the upper edge of the sides and a single sup porting rimat the bottom of the-pan which is an extension of the outer thickness ofmetal, thereby producing a very rigid yet light pan particularlydesigned to be enameled and in which a great saving of enamel isobtained, since the surface of the metal lying in contact requires noenameling.

With these and other objects in view, our invention consists in thenovel construction of a pan illustrated in the accompanying drawingsforming part of this specification, and as hereinafter described andclaimed.

In the drawings,-Figure 1 is a top plan view of our improved pan. Fig. 2is a longitudinal vertical section taken on line 2-2, Fig. l; the coverbeing elevated out of contact with the pan proper.

The pan is preferably oval in contour and comprises a body A and a coverB. The body is formed of a single sheet of metal drawn and stamped tothe desired shape. The central portion of the sheet is dished to form aconcavo-convex bottom C and the vertical sides D of the dished portion,the sides merging into the bottom by curving the metal at this point,whereby sharp corners or angles are avoided.

The marginal portions of the metal sheet are bent downward around thedished portion to surround the same, as at E, and to avoid sharp cornersthe metal is provided with a hollow rim F where it is recurved so that agradually rounded surface is obtained at the edge of the pan. Therecurved or enveloping portion of the metal lies in physical contactwith the sides of the dished portion from the hollow rim to a pointwhere said sides merge into the bottom, at which point it is bulgedoutward with an ogee curve, as at G, and its lower end serves as asupportingrim, designated H and having an outwardly curved base-flange Icoiled upon itself, as at J.

By enveloping the dished-portion of the pan with the recurved mar inalportion of the metal sheet, the sides of tie pan are made of twothicknesses of metal, whereby the dished portion is reinforced andgreatly stiffened. Moreover, the hollow rim extends beyond the surfaceof that portion of the outer thickness of metal lying in contact withthe sides of the dished portion so that the metal is curved inwardunderneath the rim, which with the shoulder formed by bulging the metalat G, greatly stifiens the pan and avoids all tendency of the recurvedportion spreading and moving away from the sides of the dished portion.It is also to be noted that, by bulging the recurved portion of themetal outward where itleaves the sides of the dished portion, a groove Kis formed of sufiicient size to enter with a wash-cloth to thoroughlyclean the pan at this point.

The construction above described pos sesses further advantages, such assaving in enamel owing to the recurved portion of the metal sheet lyingin contact with the sides of the dished portion of the pan and theuality of properly receiving and retaining t e enamel wit out tendencyto chip.

The dished portion of the pan is depressed to a plane slightly above t eplane of the lower edge of the supporting rim so that when placed upon astove or in an oven, the concavo-convex bottom will be elevated from thestove or bottom of the oven, as the case may be, and the heat retainedwithin the space surrounded by the supporting-rim.

The cover B is formed of a single sheet of metal and is also of ovalformation of slightly diminished size so that its lower edge fits intothe body of the pan; it having a bead L near its lower edge which servesas a stop to limit the extent to which it enters the body. Suitablehandles M and N are provided for the cover and body, respectively, sothat they may be conveniently handled.

The advantages of this invention are directly attributable to theparticular and novel construction of the pan, which is inexpensive tomanufacture, very durable and rigid, and perfectly sanitary.

Having thus described our invention, what we claim is.

1. A cooking-pan adapted to receive a coating of enamel or the like,formed of a single sheet of metal having a central depressed portionproviding a concavo-convex ottom and side walls merging into said bottom, a recurved portion surrounding said side-walls and in physicalcontact therewith and connected at its upper edge with the upper edgesof said side walls by a hollow rim, said recurved portion terminating ina supporting rim whose lower edge is in a plane beneath the lowest pointof said concavo-convex bottom.

2. A cooking-pan adapted to receive a coating of enamel or the like,formed of a single sheet of metal having a central depressed portionproviding a concavo-convex ottom and side walls merging into saidbottom, and a recurved portion surrounding said side walls and providinga hollow rim at the upper edge of the pan, said recurved portion lyingin contact with the side walls of said central depressed portion andbeing ofi-set where said side walls merge into said bottom to form asupporting-rim.

3. A cooking-pan adapted to receive a coating of enamel or the like,formed of a single sheet of metal having a central depressed portionsurrounded by a recurved portion in physical contact with the sides ofsaid depressed portion and connected with the upper edge of saiddepressed portion by a hollow rim extending out beyond the outer surfaceof the adjacent portions of said recurved portion.

4. A cooking-pan adapted to receive a coating of enamel or the like,formed of a single sheet of metal having a central depressed portionproviding a concavo-convex bottom and side walls merging into saidbottom, and a recurved ortion surrounding said side walls and providinga hollow rim at the upper edge of the pan, said recurved portion lyingin contact with the side walls of said central depressed portion andbeing bulged outward where said side walls merge into said bottom toform a supporting-rim.

5. A cooking-pan adapted to receive a coating of enamel or the like,formed of a single sheet of metal having a central depressed portionproviding a concavo-conveX bottom and side walls merging into saidbottom, and a recurved portion surrounding said side walls and providinga hollow rim at the upper edge of the pan, said recurved portion lyingin contact with the side walls of said central depressed portion andbeing offset where said side walls merge into said bottom to form asupporting-rim, said supporting-rim having an outstanding flange formedby curving the lower marginal portion thereof outward and curving theflange upon itself. 7
